Nanometric Scale Temperature Detection Thanks to Chemical Thermometers

Temperature map of a gold nanowire on a silicon substrate, Joule-heated by the application of an electrical current of 7 mA, obtained through infrared thermography (top) and a spin-crossover surface thermometer (bottom). While heating remains undetectable in infrared due to low thermal and spatial resolution, temperature distribution is well resolved using an SCO-based thermometer, which reveals a "hot spot" resulting from a malfunction of the component.
